Find the Total surface area of the triangular prism below.
zaharov [31]

Answer:

The surface area of any prism is the total area of all its sides and faces. A triangular prism has three rectangular sides and two triangular faces. To find the area of the rectangular sides, use the formula A = lw, where A = area, l = length, and h = height. To find the area of the triangular faces, use the formula A = 1/2bh, where A = area, b = base, and h = height. Once you have the areas of all sides and faces, you simply add them together to get the surface area.

Step-by-step explanation:

Formula

Area of a triangle

A = 1/2bh

Area of a rectangle  

A = lw

Surface area of triangular prism  

SA = bh + (s1 + s2 + s3)H

HARDEST QUESTION IN THE ENTIRE WORLD. CAN YOU SOLVE?
makvit [3.9K]
Hello, there!


The distance from Mia to Eva is 15 feet, and the distance from Mia to Abigail is 25 feet. A triangle is drawn connecting the positions of Mia, Abigail, and Eva. How far is Eva from Abigail if the angle marking Mia’s position is 50°?



Let's pretend that:


Mia is point A


Abigail is point B


Eva is point C.


The answer is 19.2 feet.


That means that the answer is C


I have drawn the triangle to scale, and attached it below. That way, you can see how I got this answer.



I hope I helped!


Let me know if you need anything else!

Help me pls what is the rate of change and the function​
KengaRu [80]

Answer:

Step-by-step explanation:

Rate of change of a function between x = b and x = a,

Rate of change = \frac{f(b)-f(a)}{b-a}

From the given table,

Rate of change of the given function between x = 3 and x = 5,

f(5) = -26

f(3) = -2

Rate of change = \frac{-26+2}{5-3}

                          = -12

Since, rate of change for the given function is constant, function is a linear function.
